Facebook introduced app ratings and negative feedback metrics to the app insights tool today as a way to help developers gain a better understanding of how users respond to their apps.

Detailed on developer blog post, these new metrics allow developers to go beyond monitoring growth trends and gain. Facebook has used this data to determine what appears in News Feed, but developers previously did not have the ability to see these insights or track their performance over time. Facebook says app ratings and negative feedback will also factor into what apps appear in the recently announced App Center.

The new app ratings dashboard in app insights will show developers how users have rated an app on a scale of one to five stars. Developers can view ratings as absolute numbers or relative percentages across different demographics, including age and gender, country and locale. Before, developers could only see their apps’ average overall rating and could not determine how the rating varied over time or by demographic.

The negative feedback metric will show developers how many times people have chosen to hide stories from an app, reported stories as spam or blocked an app completely. These reports are the same ones Facebook uses in its automated systems to detect spam on the platform, so it will be useful for developers in monitoring their performance over time. The insights will include the ratio of negative feedback to total impressions as well as an overview chart that displays green when an app is doing well and yellow when an app has reached a level for concern. Developers will even be able to compare the type of feedback they get from specific action types, as well as compare how users versus non-users respond to their content.
